Benabou also says he was mistakenly told that he wasn't entitled to receive overtime despite working 14 to 18 hour days between March 2011 and October 2012.

An email message sent to Bieber's publicist was not immediately returned.

Benabou is seeking unspecified damages on the assault and battery claims and $421,261 in unpaid overtime, vacation and other wage benefits.

"For nearly two years Mr. Benabou devoted himself completely to ensuring Mr. Bieber's personal safety," Benabou's attorney, Ilan Heimanson, wrote in a statement. "Mr. Benabou deserved, as does any employee, to be treated with respect, dignity and in accordance with the law. Unfortunately, he was not. "

Bieber's album "Believe" ranked No. 6 in 2012 sales with more than 1.3 million units sold.

In October Los Angeles prosecutors declined to file charges against Bieber after finding insufficient evidence that he punched and kicked a photographer outside a movie theater near his home in Calabasas, Calif., a month earlier.
